The United States has named the UK-based Palestine Action group, which has been banned by the British government, as a "specially designated global terrorist" organisation.
The US also issued sanctions against the group, saying the move was for supporting "an act of terrorism."
Set up in 2020, Palestine Action is appealing against the UK government ban which has led to thousands of arrests. Rights groups have decried the ban, saying it was aimed at criminalising dissent.
Palestine Action's stated goal on its website is to end "global participation in Israel's genocidal and apartheid regime."
It gained visibility after Israel launched its genocide in Gaza following the October 7, 2023 attack by fighters from Palestinian resistance group Hamas in southern Israel that were once Arab farms and hamlets before the creation of Israel.
The US decision follows a decision by the UK government in July 2025 to proscribe the group under the Terrorism Act.
That ban came after activists entered a Royal Air Force base and spray-painted two aircraft.
The group also targeted Elbit Systems, an international weapons electronics company with ties to the Israeli military.
The United Kingdom's Supreme Court has said it will hear an appeal against a lower court ruling that Britain's decision to ban Palestine Action as a terrorist group was lawful.
Italy-based group designated
Since coming to power for his second term, US President Donald Trump has issued orders for his government to designate what it terms "far-left" groups as terrorist organisations.
Wednesday's US action also designated Italy-based Autistici/Inventati (also known as A/I Collective) and pro-Palestine group Masar Badil as "terrorist" organisations.
US State Department spokesperson Tommy Piggot declared all three groups, including Palestine Action, as being "violent far-left terrorist groups."
US Treasury Secretary Scott Bessent said Washington would bring "the full weight of our economic tools to bear" against far-left groups.
"Political terrorism has no place in our society, and we will continue to cut the financial lifelines of these groups until they are eliminated."
